Abstract
The utility model relates to a water-cooling quick-open manhole device for a flue type waste heat boiler. The water-cooling quick-open manhole device comprises a lower manhole cylinder. A lower flange is arranged on the lower manhole cylinder. The two ends of the lower flange are at least provided with one fixing ear plate each. An upper manhole cover plate is fixedly connected to one fixing ear plate through a right angle rotary arm. Pull rods are fixedly connected to the fixing ear plates on the other side. The upper ends of the pull rods run through fixing holes in the upper manhole cover plate and fix the upper manhole cover plate through fixing devices. The lower manhole cylinder and the upper manhole cover plate are both of an inner-outer ring sandwich type structure. A cover plate water inlet and a cover plate water outlet are formed in a sandwich layer of the upper manhole cover plate. Baffling partition plates are arranged in the sandwich layer of the upper manhole cover plate. The service life of the quick-open manhole device is effectively prolonged, the phenomenon of yellow smoke and dust overflow caused by manhole burn-through is avoided, and the labor intensity for maintaining the quick-open manhole device is greatly relieved. The combined structure facilitates assembly and disassembly and is high in applicability.
Description
Technical field
The utility model relates to a kind of flue type waste heat boiler steelmaking equipment, specifically a kind of water-cooled quick opening manhole's device for flue type waste heat boiler.
Background technology
On steelmaking equipment, flue type waste heat boiler is installed on converter evaporation cooling air flue with water-cooled quick opening manhole device, is positioned at stage casing and three curved, four crooks of flue, its objective is the device for deashing, scarfing cinder or maintenance use in flue.Whether manhole device's design and use are reasonable, directly affect temperature and environment in steelshop, affect the rhythm of production of factory.If manhole device design is good, also can alleviates workman's switch manhole and safeguard the workload of manhole.
The manhole device that steel mill is used mostly is at present generally flange bolt fastening, the resistance to material of upper cover plate inner side cast, and some steel mills adopt the mode of the embedded fire-resistant cotton of cover plate; Yet in actual use procedure, the resistance to material that mostly occurs comes off, fire-resistant cotton comes off, thereby cover plate is burnt by high-temperature flue gas, or occurs the phenomenons such as weld cracking that manhole cylindrical shell is connected with flue; Finally cause when bessemerizing, a large amount of tobacco and flare from burning, cracking emits outward, it is severe that site environment becomes; Because the problems referred to above often appear in manhole, cause workman to increase the maintenance workload of manhole, it is large that the labour intensity of high temperature service becomes simultaneously.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of reasonable in design, simple in structure, water-cooled quick opening manhole device for the flue type waste heat boiler of good sealing effect and long service life.
In order to solve above technical problem, the utility model provides water-cooled quick opening manhole device for a kind of flue type waste heat boiler, comprise manhole lower shell, described manhole lower shell is provided with lower flange, on described lower flange, two ends are at least respectively provided with a fixedly otic placode, and one of them is fixedly fixed with manhole upper cover plate by right angle pivoted arm on otic placode, and opposite side is fixedly fixed with pull bar on otic placode, and described pull bar upper end is through the fixing hole on manhole upper cover plate, and by the fixing manhole upper cover plate of fixture; Described lower shell and manhole upper cover plate are Internal and external cycle sandwich type structure, and described manhole upper cover plate interlayer is provided with cover plate water inlet and cover plate delivery port, in described manhole upper cover plate interlayer, are provided with baffling dividing plate.
The technical scheme that the utility model further limits is: water-cooled quick opening manhole device for aforesaid flue type waste heat boiler, and the fixture of pull bar upper end comprises wedge, described wedge is through the rectangular opening matching with wedge of pull bar upper end.
Further, water-cooled quick opening manhole device for aforesaid flue type waste heat boiler, described baffling dividing plate is three, and is dislocation placement.
Further, water-cooled quick opening manhole device for aforesaid flue type waste heat boiler, is provided with asbestos layer of cloth between described lower flange and manhole upper cover plate.
Further, water-cooled quick opening manhole device for aforesaid flue type waste heat boiler, described lower shell side is provided with lower shell water inlet and lower shell delivery port.
The beneficial effects of the utility model are: the utility model is arranged to Internal and external cycle sandwich type structure by manhole lower shell, manhole upper cover plate, and water flowing is cooling, the bolt of original flange connect is made into the form that wedge inserts pull bar simultaneously, effectively extended manhole device's service life, avoided burning because of manhole the generation of the excessive phenomenon of tobacco dust causing, the work that has also greatly alleviated manhole device's maintenance is artificial.The design's fabricated structure, assembling and convenient disassembly, applicability is strong.
